A team of Johns Hopkins scientists reports in this week's issue of the Proceedings of the National Academy of Sciences
that humans can be protected against the damaging effects of ultraviolet (UV) radiation - the most abundant cancer-causing agent in our environment - by topical application of an extract of broccoli sprouts. The results in human volunteers, backed by parallel evidence obtained in mice, show that the degree of skin redness (erythema) caused by UV rays, which is an accurate index of the inflammation and cell damage caused by UV radiation, is markedly reduced in extract-treated skin.

Having more years of formal education delays the memory loss linked to Alzheimer's disease, but once the condition begins to take hold, better-educated people decline more rapidly, researchers said on Monday.
Their study, published in the journal Neurology, tracked memory loss in a group of elderly people from New York City's Bronx borough before they were diagnosed with Alzheimer's or another form of old-age dementia.

WASHINGTON - More women who have cancer in only one breast are getting both breasts removed, says research that found the trend more than doubled in just six years. It's still a rare option: Most breast cancer in this country is treated by lumpectomy, removing just the tumor while saving the breast.

China - The government is deeply concerned by reports that some Filipino students have fallen ill after eating Chinese-made milk candies, the spokesman of the Ministry of Commerce said.

Michelle Hammond and Jeremiah Holland were intrigued when a friend at the Oakland Tribune asked them and their two young children to take part in a cutting-edge study to measure the industrial chemicals in their bodies.
"In the beginning, I wasn't worried at all; I was fascinated," Hammond, 37, recalled.
But that fascination soon changed to fear, as tests revealed that their children -- Rowan, then 18 months, and Mikaela, then 5 -- had chemical exposure levels up to seven times those of their parents.

It has long been assumed that sleep deprivation can play havoc with our emotions.
This is notably apparent in soldiers in combat zones, medical residents and even new parents. Now there's a neurological basis for this theory, according to new research from the University of California, Berkeley, and Harvard Medical School.
In the first neural investigation into what happens to the emotional brain without sleep, results from a brain imaging study suggest that while a good night's rest can regulate your mood and help you cope with the next day's emotional challenges, sleep deprivation does the opposite by excessively boosting the part of the brain most closely connected to depression, anxiety and other psychiatric disorders.
"It's almost as though, without sleep, the brain had reverted back to more primitive patterns of activity, in that it was unable to put emotional experiences into context and produce controlled, appropriate responses," said Matthew Walker, director of UC Berkeley's Sleep and Neuroimaging Laboratory and senior author of the study, which will be published Oct. 22 in the journal Current Biology.
"Emotionally, you're not on a level playing field," Walker added.

Philosophers and scientists have long been interested in how the mind processes the inevitability of death, both cognitively and emotionally. One would expect, for example, that reminders of our mortality--say the sudden death of a loved one--would throw us into a state of disabling fear of the unknown. But that doesn't happen. If the prospect of death is so incomprehensible, why are we not trembling in a constant state of terror over this fact?
Psychologists have some ideas about how we cope with existential dread. One emerging idea--"terror management theory" --holds that the brain is hard-wired to keep us from being paralyzed by fear. According to this theory the brain allows us to think about dying, even to change the way we live our lives, but not cower in the corner, paralyzed by fear. The automatic, unconscious part of our brain in effect protects the conscious mind.

The Food and Drug Administration (FDA) is warning some drugs used for impotence may cause sudden hearing loss.
Erectile dysfunction including Viagra, Levitra Cialis and the blood pressure medication Revatio will now carry new warning labels about the potential risk of sudden hearing loss, reported WebMD.

Parents of severely overweight children in Britain could be sent letters warning them about the health dangers of obesity, the government said on Monday.
Letters could be sent after children are routinely weighed at primary school at the ages of five and 10.

With the latest advances in treatment, doctors have discovered that they can successfully neutralise the HIV virus. The so-called 'combination therapy' prevents the HIV virus from mutating and spreading, allowing patients to rebuild their immune system to the same levels as the rest of the population.
To date, it represents the most significant treatment for patients suffering from HIV.
Professor Jens Lundgren from the University of Copenhagen, together with other members of the research group EuroSIDA, have conducted a study, which demonstrates that the immune system of all HIV-infected patients can be restored and normalised. The only stipulation is that patients begin and continue to follow their course of treatment.
